In continuation of our studies of 3,3-sigmatropic reactions, we have discovered the facile amino-Claisen rearrangement of the N-allyl-enamine system in pyrazolin-5-ones (1). Recent reports (2, 3,4) on the analogous examples of the amino-Claisen rearrangement prompt a preliminary report of our work o
